CHARLES HENRY LISTER, OF NORTH ST. PAUL, MINNESOTA.

INC LINED ELEVATOR.

Specification of Letters Patent.

Application filed January 21, 1915. Serial its. 3,500.

To all whom it may concern:

I Be it known that 1, CHARLES HENRY- LISTER, siding at North St. Paul,in the county of a citizen of the United States, re

Ramsey and State of- Minnesota, have invented new and usefulImprovements in Inclined Elevators, of which the following My inventionrelates to improvementsin inclined elevators. 4 Its object is toprovidel'an inexpensive, durable and efiicient device for transferringarticles from alower to a higher elevation,

' said device being supplied with improved packages, carrier to andnovel means for transferring boxes, or. other objects/from a gravity theelevator trackvwithout injury. A further object isto provide in an eleavator of this kind a simple'and inexpensive stationary track or floorupon'jwhich objects may be conveniently retained and moved.

A further object is to provide improved carrying mechanism. forelevators of this,

type, having means tension thereof.

In the drawings Figure 1 isa side elevation illustrating my improvedelevator and showing .portions of adjacent conveyors; Fig.2 is anenlarged fragmentary plan view thereof; Fig. 3 is a, sectional viewtaken on I the line3+3 of Fig. 2,'the chains being omit- Fig. 4 isa line5.-5 of Fig. .2.

ted to permlt a view of certainother parts;

tical sectional view in detail taken on the 'Referrifi to-the thecurvedreceiving section of thefra'me a of the elevator;'B- the'inclinedintermediate section thereo fi an e C the curved delivery section ofsaid frame.

lation by the bars '13 upon the inner sides thereof; 7 The w ays of'one-sectioncommunicatew1th the respec- 1s "channel bars =D indicates afeeding convfeyer of-the or- .dinary gravity type for moving art1cles'to the elevator and E designates a similar conveyer for receivingarticles from the upper-f. end tions A and 0 comprises right framesecandl-left by the. numerals 10 and. are united in parallel re- 12 andare formed with er and lower channeled W'ays13and of the elevator. Eachofv the castings indicated 11. .Said castings tive ways-ofhe othersection through 14, which are'secured ini-parout the length of theelevator.

for easily adjusting the sectional view in detail taken on the line 45-4of Fig. 1 and Fig. 5 is a ver- 7 accompanying drawings; ,I'have'use thereference letter A to indicate iii) of the tpower elevator,

such

allel relation bythetie bars 'l5 and spacing bars 12, all of whichformthe intermediate section B of the elevator frame." A revoluble shaft 16on the section 0 is supplied Wltll'SPlOCkGb wheels 1T, and" with a gearwheel 18. This gear wheel meshes with the ear wheel 19 on thecountershaft 20 in said rame'section and a "friction wheel 21 on ,saidcountershaft bears against the powerdrivenfriction wheel 22. The sectionA is also provided with a revolublelshaft '23 having sprocket wheels v21 thereon.

endless: traveling chain 25, consisting of;-

links 26?, joined by pins 27, having roller bearings 28 thereon, passesover the sprocket wheels 17 and24: at each side of the elevator saidsprocket wheels by'the ways 13 and 13 in the frame.- Transverse flightcarriers 29 are secured at their ends upon the opposite chains and. arespaced well apart through- A- sheet metaltrackor floor 30 is mountedupon the spacing bars 12 and 12 in position between the upper and lowerruns of the chains 25,-

and said floor is corrugated longitudinally to minimize the frictionalsupporting'sur- 'mounted at their ends upon the sprocket Patented Oct.10, aerial frame and is guided in its travel between i wheels 24. Thefunction of said roller is to support and impel objects .in their travelfrom the gravity conveyer D to the fioor30 and the conformation thereofurnishes a roller bearing surface over which objects may freely passeither at a. greater'rate of speed than the peripheral movement of theroller, or upon which objects may be retarded and move sl'owlywithoutresulting damage. To provide means for adjusting the ten sion of thechains 25, I place bearings 31 for,

the shaft 23 upon slidable rods 32, which are threaded at 33. .One ofthe rods 32 is movably mounted in the supports 34 at each side of thesection A and nuts 35 on the threaded portion 33 of each rod abutagainst opposite sides of one Qfsilld. supports 3% to supplymeans forshiftinglsaid rod in either direction and secur ng the same, whereby thedistance between the sprocket \vheels 17 and 24'Jr1' ay 'be increased ordiminished, thus tightening or loosening the chains 25.

Having described my invention, what I claim as new and desire to protectby Letters Patent is:

1. The combination with a conveyer of an inclined elevator comprising aframe, a track or flooron said frame, a composite roller having itsperiphery formed of a series of transverse revoluble rods, adapted totransfer packages from said conveyer to he floor of the elevator, andtraveling carriers cooperating with said roller to advance packages uponsaid floor.

2. ',In an elevator, a frame having an intermediate inclined portion andsubstantially horizontal end portions, said frame being formed with anupper .andlower channeled way on either side thereof, a power shaft onthe upper end of the frame having driving sprockets thereon, an idlershaft on the lower end of the frame, -a package receiving roller on saidshaft, comprising a series of peripherally supported revolubly mountedrods, sprocketwheels on the roller, an endless chain guided by the waysat each side of the frame, each ofsaid chains passing over one of thedriving sprocket wheels and a sprocket wheel on said roller, atrack orfloor upon said frame, and transverse carriers connecting the chains atintervals.

3. The combination with a grav ty carrier frame, a revoluble shaft onsaid frame, a

, roller carried by said shaft and consisting of a series ofperipherally arranged revolubly mounted rods, said roller beinginterposed between the delivery end of said carrier and the receivingend of the elevator, a track or floor upon said frame, and carrierscooperating with said roller to move objects upon said track or floor.

4. In an inclined elevator, a'track, carrying means for moving packagesupon said track and a receiving roller driven by said carrying means,said roller consistingof a series of peripherally arranged revolublymounted rods.

5. In an inclined elevator, a frame, a track on the frame, endlesstraveling chains joined at intervals by transverse carriers,'a shaftrevoluble in the frame near the lower end of said track, a sprocketwheel near each end of the shaft, over whichone of said chains travels.and a rollerconsisting of a series of peripherall arranged rodsrevolubly mounted upon sa d sprocket wheels.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES HENRY LISTER.
